CARD_TUPLE_PARMS

  • Article

This structure contains tuple information passed to the CardGetFirstTuple, CardGetNextTuple, and CardGetTupleData functions.

typedef struct { 
  CARD_SOCKET_HANDLE hSocket; 
  UINT16 fAttributes; 
  UINT8 uDesiredTuple; 
  UINT8 uReserved; 
  UINT16 fFlags; 
  UINT32 uLinkOffset; 
  UINT32 uCISOffset; 
  UINT8 uTupleCode; 
  UINT8 uTupleLink; 
} CARD_TUPLE_PARMS, *PCARD_TUPLE_PARMS;

Members

  • hSocket
    Handle to a socket and function pair.
  • fAttributes
    Specifies TUPLE_RETURN_LINKS to return link tuples. The first bit is 1.
  • uDesiredTuple
    Specifies the desired tuple code. If it is 0xFF, the first tuple encountered is returned.
  • uReserved
    Reserved for internal use only to maintain alignment with the CARD_DATA_PARMS structure.
  • fFlags
    [in, out] Specifies flags used internally by card services. A driver must maintain this value between calls to tuple functions.
  • uLinkOffset
    [in, out] Specifies a tuple link offset used internally by card services. A driver must maintain this value between calls to tuple functions.
  • uCISOffset
    [in, out] Specifies card information structure (CIS) state information used internally by card services. A driver must maintain this value between calls to tuple functions.
  • uTupleCode
    [out] Specifies the type of tuple found.
  • uTupleLink
    [out] Specifies a link value for tuple found.

Remarks

A driver should maintain the values for the hSocket, fFlags, uLinkOffset,**and uCISOffset members after using CardGetFirstTuple and between calls to CardGetNextTuple. Card services requires these members to resume the tuple search.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Cardserv.h.
